The impact of increased grid resolution on the mixed layer depth variability in the South Atlantic Ocean and Southern Ocean
… possible future climate conditions. Earth System Models are used to study Southern Ocean dynamics and are currently producing reliable global annual carbon uptake but have limiting seasonal abilities. These models produce dependable results on a global scale, with more conflicting results on a …

Investigation of the 3 x 2 Achievement Goal Framework in Two University Band Contexts: Scale Development and Model Fit of a Six-Factor Structure describing University Band Students’ Goal Orientations Toward Personal and Ensemble Music Performance
… the extent to which the 3 x 2 achievement goal model fits to two contexts of university band performance. Results from a pilot study informed establishment of a 19-item 3 x 2 AGQ – MP. The resulting questionnaire featured matching items with contrasting prompts in order to measure student goal …

Numerical Simulations of the Rapid Cyclogenesis Over Canada and Evolution of a Cold Front Observed on 25-26 April 1979 (sesame-Ave-Iii)
… with the cold front. A regional scale prediction model, which is the quasi-Lagrangian nested model developed by Mathur (1983) and modified in this study, was used to achieve these objectives. FGGE (First GARP (Global Atmosphere Research Program) Global Experiment) level IIIb and IIb data were used …

Elementary Teachers' Grading Practices: Does the Reality Reflect the Rubric?
… from 45 schools. Multilevel structural equation models, with students nested within classrooms, tested two models describing variance in report card grades. One model included the factors listed on the school system grading rubric along with additional factors thought to be related to grades …

An empirical examination of an integrative theory of social behavior: Some structural equation modeling tests
… was proposed in this study. Structural models of social behavior which posited specific relations between important constructs from each of these theories were examined. Using class attendance and condom use as target behaviors, multiple items were developed to measure each of the …

EFFECTS OF DOMESTIC VIOLENCE EXPOSURE IN COLOMBIAN ADOLESCENTS: PATHWAYS TO VIOLENT AND PROSOCIAL BEHAVIOR
<p>A multidimensional model of associations between domestic violence exposure and risk of violence and prosocial behavior was tested in a sample of Colombian adolescents, with attention to impulsivity and substance use problems as mediators of these associations. A representative sample of 1,152 …

The impact of crime on birth weight: exploring the definition of residential environment
… prior to birth. Results from linear regression models do not support the hypothesis that reported crime influences birth weight in either the distance-defined or census defined PRE model. However, while measures of model fit are comparable across PRE definitions, non-nested model specification …

The Unified Approach for Model Evaluation in Structural Equation Modeling
Practical fit indices have been widely used for model fit evaluation in Structural Equation Modeling. This dissertation discusses the properties of the fit indices including their influencing factors. These properties prevent researchers from deriving one-size-fit-all cutoffs for the fit indices. …

Tides of Cooperation: The Ebb and Flow of Regional Cooperation in Latin America
… a large-N statistical analysis utilizing a cross-nested model to capture variance within and between organizations, it finds evidence that asymmetric distribution of investment and trade hinders political indicators of cooperation. Additional in-depth case analysis of the Andean Community and …

Bayesian Hidden Markov Models for finding DNA Copy Number Changes from SNP Genotyping Arrays
… number sequences, is developed for estimating model parameters. Numerous versions of Bayesian HMMs are explored, including a discrete-time model and different models for the instantaneous transition rates of change among copy number states of a continuous-time HMM. The most general model …

Understanding The Variability Of Circulation And Water Quality At Experimental Oyster Leases In The Mississippi Sound Using A High-Resolution Nested Modeling Approach
… oysters in the Mississippi Sound (MSS). Two-way nested simulations using ROMS within COAWST modeling framework have been run with improved forcings to analyze circulation, salinity and temperature variability within and around the lease areas under the extreme freshwater inflow from Bonnet Carré …

Dynamic wetting of soft materials and applications of dynamic tensiometry
… oleophobic fabrics is analyzed using a nested model with n levels of hierarchy that is constructed from modular units of cylindrical and spherical building blocks. For a plain-woven mesh comprised of chemically treated fiber bundles (n = 2), the tight packing of individual fibers in each …
